= CUI Module

The module `cui` (`link:https://freeradius.org/rfc/rfc6572.html#Chargeable-User-Identity[Chargeable-User-Identity]`) writes
`link:https://freeradius.org/rfc/rfc6572.html#Chargeable-User-Identity[Chargeable-User-Identity]` log to an SQL database.   It uses the `sql`
module to do the bulk of the work, but has custom schemas and
queries.

  * Schema is in `raddb/sql/cui/<DB>/schema.sql`
  * Queries are in `raddb/sql/cui/<DB>/queries.conf`



## Configuration Settings


dialect:: The dialect of SQL you want to use, this should usually match
the driver below.

NOTE: If you're using rlm_sql_null, then it should be the type of
database the logged queries are going to be executed against.



driver:: The sub-module to use to execute queries. This should match
the database you're attempting to connect to.

There are CUI queries available for:

[options="header,autowidth"]
|===
| DB          | Driver
| SQLite      | rlm_sql_sqlite
| MySQL       | rlm_sql_mysql
| PostgreSQL  | rlm_sql_postgresql
| Log to disk | rlm_sql_null
|===



[NOTE]
====
For dialect `mysql` and `postgresql` the following information should be provided:

====


sqlite { ... }:: SQLite configuration.



logfile:: Write CUI queries to a logfile. Useful for debugging.



pool { ... }:: persistent connections to external resources.



cui_table:: The name of the database table to use for store.



sql_user_name:: `SQL-User-Name` is used as the user for SQL queries.
Normally it is the same as `link:https://freeradius.org/rfc/rfc2865.html#User-Name[User-Name]`, but sometimes it needs to be different.
Then instead of editing `link:https://freeradius.org/rfc/rfc2865.html#User-Name[User-Name]` (*which we don't recommend*), you can
set `SQL-User-Name` to the new value.



.Load the queries from a separate file.


== Default Configuration

```
sql cuisql {
	dialect = "sqlite"
	driver = "${dialect}"
#	server = "localhost"
#	port = 3306
#	login = "radius"
#	password = "radpass"
#	radius_db = "radius"
	sqlite {
		filename = ${radacctdir}/cui.sqlite
		bootstrap = ${modconfdir}/${..:name}/cui/sqlite/schema.sql
	}
#	logfile = ${logdir}/cuilog.sql
	pool {
		start = 0
		min = 4
		max = 10
		spare = 3
		uses = 0
		lifetime = 0
		idle_timeout = 60
	}
	cui_table = "cui"
	sql_user_name = "%{User-Name}"
	$INCLUDE ${modconfdir}/${.:name}/cui/${dialect}/queries.conf
}
```
